I am getting these crash reports on Xcode organizer from users of the app. It does not show any line of my code in the crash, looks like it crashed on init. I do not know how to progress with the debug. Can you please help:

I had a similar issue. In my case, the issue was that I changed the watch app extension name, so it doesn't include the underscore character. After this, I experienced this crash.
The solution was, to go into the storyboard file of the watch app extension, and in the identity inspector of the existing view controllers, I just retyped the name of the custom class names, and the module updated automatically. After this, it worked. Hope it works for you as well.
Just FYI. The issue that I had was one of those embarrassing ones.
The storyboard had "Inherit Module From Target" on.
However, the default layout that Apple creates, has the executable in a separate (Extension) target.
I need to uncheck that box, and explicitly reference my extension target.
D'oh!

I'm trying to integrate FB into an existing iOS app.
I've modified the HelloFacebookSample app to use my app ID, display name, and bundle identifier. I can run it and post from it just fine (running in the iOS 6 emulator). So that leads me to believe my settings on developers.facebook.com are correct.
Next I looked at the code in the app delegate and view controller in the sample and duplicated it in my own code. The first bit of Facebook code that gets executed is in the app delegate, in applicationDidBecomeActive:. I execute the same two lines as the sample app:
[FBAppEvents activateApp];
[FBAppCall handleDidBecomeActive];
If I run my program, I eventually get EXC_BAD_ACCESS (code=2, address=0x0). In the debug navigator I see:

If I remove [FBAppCall handleDidBecomeActive] I get the same result. So this seems to be a result of [FBAppEvents activateApp].
If I remove [FBAppEvents activateApp], which I understand to be optional anyway, and only call [FBAppCall handleDidBecomeActive], I can launch the app. But then when I try to create an instance of FBLoginView in my view controller:
FBLoginView * loginview = [[FBLoginView alloc] init];
I get the same error (EXC_BAD_ACCESS (code=2, address=0x0)):

Don't be fooled by the fact that I'm obviously not creating my FBLoginView in viewDidLoad. The point is that the first call to anything that tries to do anything with my Facebook session fails in the same way. It looks like it's trying to do something with a handler in both cases. The identical code works with MY Facebook identifier, bundle ID, etc. in the sample code, but doesn't work in my app. I'm suspecting compiler/linker settings or some other configuration difference between my app and the sample, but I'm not sure where to begin to look. Everything I've looked at looks the same between my app and the sample.
I've tried a lot of different ways to open a Facebook session and get the permissions I need, but they all fail the same way. This seemed like a good one to post here since the sample works but the same code in my app doesn't.
Thanks for your help.
EDIT: I see in my build settings that the sample app uses ARC. I do not. I'm hesitant to convert a large, functioning app at this point in its lifecycle.
Very infrequently, our app is crashing because it receives SIGKILL. The circumstances are different, but the backtrace is always the same:

#22 0x000027c5 in start ()
How would I go about finding out what is causing this crash?
The SIGKILL is sent to apps for any kind of exceptions. Se we have to make an educated guess what the exception reason would be in this case. In the above case it looks like accessibility is checking for a certain kind of pasteboard type to be present.
Since this is happening in Apple code most likely this is a bug in iOS, because the containsPasteboardTypes: method should never throw an exception. Only possibly if the passed parameter is nil, but then the bug would lie in UIAccessibilityTextFieldElement which too is Apple's responsibility.
Long story short: you need to file a radar. As a workaround you can add an #try block around the offending operation. This would catch and ignore the exception.
My app crashes only in simulator , it doesn't crash on device.
it crashes in simulator and gives me nothing except this :

Why is this happening?
Thanks.
Set NSZombieEnabled, MallocStackLogging, and guard malloc in the debugger. Then, when your App crashes, type this in the gdb console:
(gdb) info malloc-history 0x543216
Replace 0x543216 with the address of the object that caused the crash, and you will get a much more useful stack trace and it should help you pinpoint the exact line in your code that is causing the problem.
See this article for more detailed instructions.
Another idea is to try turning off auto-correction in the simulator Settings App.
I'm using cocos2d and I load all my sprites and scenes before my game. However, once loaded, it seems if I click to start the game too quickly I get this crash:
malloc: *** error for object 0x65cdbb4: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
So I did what it suggested, recreated the crash and the stack shows this:

I am working on simple iphone application. where i am working on two views. I pushed the other view controller first and when i am removing the current view as to go back to the old view controller i am getting [CALayer retain]. EXEC_BAD_ACCESS.
In gdb, i tried backtrace command to see the problem which i have given below, but i am not able to find any. If anyone can help me out with this it will be great.

Thanks,

Sounds like you're also explicitly releasing something that you've already autoreleased.
Use Instruments and enable Zombies. This will trace where each object was retained and released and will hell you diagnose where the extra release is occurring.
